- Bumped VTF files to version 7.4
- Added $halflambert and a few other VMT flags ($halflambert softens the shadows on the model. The other VMT edits really do nothing.)
- Removed unused and unedited copy of Portal 1's arms model

- Renamed original model to "v_hands_portal1"
- Added new/edited arms variant "c_portal1_arms" that is compiled like Gmod's viewmodel arms (following the Gmod Wiki's example files)
- Updated thumbnail

Fixed regression with Lua script in previous update.

Reduced addon size by around 1MB by removing unnecessary data (mipmaps, thumbnails, and alpha channel) from the two texture files.

- Edited the script to remove the Portal 1 requirement, as the textures are included in the addon as of the previous update. The arms should now always appear as an option in the edited version of the Enhanced PlayerModel Selector.

- Added the unused textures from Portal 1 and 2 to the addon, thus removing arbitrary requirement have two entire games installed just for a tiny Gmod addon to not have broken textures.
- Updated thumbnail. The AR2 is the only stock weapon that shows the forearm tattoo at the right angle, but the thumb on the right hand looks weird. Oh well.

- Removed script which checked for Portal 1 and 2 and printed a chat message.
- Added script which silently adds the arms to the playermodel list if Fesiug's Edit of the Enhanced PM Selector is enabled and Portal 1 is mounted.
- Removed pre-rendered spawnicons to reduce addon size.
- Removed unnecessary VTX files ("dx80" & "sw") to reduce addon size. If you're on a system that somehow still supports Steam and Garry's Mod but not DirectX 9, tough luck.
